Johannes Cuspinianus (December 1473 – 19 April 1529), born Johan Spießhaymer (or Speißheimer), was an Austrian humanist, scientist, diplomat, and historian. Born in Spießheim near Schweinfurt in Franconia, of which Cuspinianus is a Latinization, he studied in Leipzig and Würzburg. He went to Vienna in 1492 and became a professor of medicine at the University of Vienna. He became Rector of the university in 1500 and also served as Royal Superintendent until his death.
A leading scholar, he was the author of De Caesaribus et Imperatoribus and was also given a poet’s laurel wreath by Maximilian I, Holy Roman Emperor. He was part of an intellectual circle that included Joachim Vadianus and Stiborius. He rendered important service as the discoverer and editor of classical and medieval historical texts. His unfinished Austria (1527-8) was an important historical-geographical regional survey of Lower Austria.
In 1490 he matriculated at the University of Leipzig, went to the University of Vienna (1493) to continue his humanistic studies, and in 1494 entered there on a course of medicine. At this early age he edited the "Liber Hymnorum" of Prudentius, and made a reputation by his lectures on Virgil, Horace, Sallust, and Cicero.
He was acquainted with Emperor Frederick III. In 1493, in reward for a panegyric on the life of St. Leopold of Austria, he was crowned as poet laureate and received the title of Master of Arts from Maximilian. Soon after this he was made a doctor of medicine, and in 1500 rector of the university.
